Make the Pasted Text Take the Destination's Style
The Problem:
When I add text from another document or web page into a Word document, I want the current style in my Word document to control the style of the pasted text. But instead, I end up with the pasted text being in "Normal (Web)" style or some other style with the wrong font.
The Solution:
In Word 2003 and Word XP, you can click the Paste Options Smart Tag and choose Match Destination Formatting from the pop-up menu to make the pasted text take on the current style.
If you've turned off Smart Tags, or if you're using Word 2000, you're pretty much stuck using Paste Special to paste in the text without any formatting (choose Edit 
Paste Special Unformatted Text), unless you're prepared to create a macro for doing so. If you do a lot of pasting, creating a macro might be worthwhile. When you paste unformatted text, it receives the style currently applied to the paragraph in which you paste it.
